Plonk Adware. Not in description.
It works on the EVO 3d but the values it gives do not compare well with a real light meter. I will not complain since it is free.
Lux meter If all you need is a lux value it worked on the front camera on my razor maxx. It's close to my sekonic meter. Would not use for a professional light meter.
